|Purpose:||Controlling Fossil's MetaWatch from Linux|
For those unfamiliar with the MetaWatch, have a look at their website. The MetaWatch is an intelligent wrist watch based on a TI MSP430 microcontroller accompanied with a Bluetooth module. For some more details you can visit my Metawatch internals page.
This labs project is about developing a Linux based client software for the MetaWatch which can later on probably also be used with other similar devices. My current design gola is to create two major parts:
Currently the protocol implementation is almost complete, as far as the protocol is implemented on the watch already. I have the library API structure implemented so that the architecture is clear but still some functions missing. The library also has the already mentioned convenience functions already implemented using an abtsract drawing buffer, drawing functions for the buffer and converter functions to convert the drawing buffer into a watch buffer for the LCD or OLED displays.
to make testing a little easier I started a GTK+ based GUI application which already uses the library, a glib mainloop (GTK) and GIOchannel for the I/O.
The GIT tree is available at http://git.kernelconcepts.de/?p=metawatch.git;a=summary
I will also at some point try to port this to mobile devices like Nokia N900.
